| Recently,investigation on the multifunctional composite nanomaterials has attracted increasingly more attention in the field of materials science. Compared to the single-function nanomaterials, multifunctional nanomaterials with special structures and various functions usually have more extensive applications. Among a variety of preparation methods of nanomaterials, electrospinning can produce composite nanomaterials with non-toxic, low pollution and high flexibility, with the feature of simple operation, strong controllability and easy industrialization. Moreover, a variety of materials with different properties can be assembled via the special method to obtain the ideal multifunctional materials. Nanomaterials with special morphologies can be successfully fabricated via electrospinning, and these nanomaterials are endowed with optical, electrical, magnetic and mechanical properties. Hence, it is a meaningful subject of study to fabricate multifunctional nanomaterials with special morphologies and to investigate their properties.In this dissertation, Eu(BA)3phen/PANI/Fe3O4/PVP, Tb(BA)3phen/PANI/Fe3O4/PVP photoluminescent-electrical-magnetic trifunctional flexible hollow nanofibers and[Eu(BA)3phen+Tb(BA)3phen]/PANI/Fe3O4/PVP electrical-magnetic and color-tunable flexible hollow nanofibers were fabricated by a one-pot electrospinning technique using a specially designed coaxial spinneret. Then the samples were systematically characterized by measurement techniques and some meaningful results were obtained, which provide new reference for further study of advanced multifunctional nanomaterials and a universal method for construction of hollow nanomaterials. The novel hollow fibrous structured trifunctional material is expected to apply in various areas of thin-film materials, display device, electromagnetic interference shielding, molecular electronics, multifunctional nanodevices and biomedical field, etc. |
